I don't find elves, dwarves, or qunari being fictional making the idea of more inclusion for other points of view and romances in Dragon Age "absurd". I don't see the harm in a female dwarven love interest, or a Tal-Vashoth love interest, aside from the issue of the prospective women not fitting the "ideal" bodytype that seems to be restricted for the potential love interests a player can pursue in Dragon Age.
I don't see any harm in it either. I don't see any harm in asking for it either because you think it will be interesting and you like being an elf in the Dragon Age setting.
I do not, however, consider it equivalent to trying to include LGBT content (which frankly, could also go to Elves, Dwarves, and Qunari, so I'm not really sure that the race is the issue here) and consider it much more of a "nice to have" than an actual "right thing to try to do."
It's reasonable to wonder if we have an inclination not to do so because of the body types, although I think that this argument would have more merit if we had more racial companions anyways. As is, we don't have many racial companions (male or female) which if you like those races, feel free to be upset about. But please don't equate the lack of that type of content as equivalent to the lack of LGBT content because I simply do not think that that is the case.
I consider them very different issues with different degrees of responsibility for whether or not there's a justification for including the content. Sorry.
